Appl. No.:

11/449877

Inventors:

David H. Shields - Van Nuys CA, US

Abstract:

A hand-portable manually operated back-massager, the U-Massage™ implement comprises a rigid frame critically configured as to facilitate a unique advantageous transitional-fulcrum principle, —whereby user can easily induce a much greater amount of massage-pressure and acupressure as well if desired. The basic notion of my transitional-fulcrum employs a gliding shoe mounted at the lower-terminus of my inverted J-shaped implement's front-leg, whereby the user is enabled to merely tilt the upper portion of the implement forward as to thereby realize a tremendous leverage advantage upon their back as the masssage-roller arranged at the lower-terminus of the implement's back-leg is caused to thrust into the user's back-musculature with far greater emphasis as compared to conventional back-massagers of this sort. While including a number of accessory options, including both motorized and heated iterations, serving to substantially enhance the functional scope and effectiveness of my basic instrument; —my disclosure also sets forth generic-variant embodiments better facilitating usage by persons of greater body variances, as well as folding in a spatially compact manner.

Abstract:

A passive anchor latching mechanism which allows its user to attach a moog line to an anchor without using a secondary mechanism such as a remotely operated vehicle to attach the cable or anchor wire to the anchor. The passive anchor latching mechanism comprises three elements: (1) a latch ring which may have a tether line removably coupled thereto; (2) an anchor post extending vertically upward from the top of the anchor; and (3) a crown line attached to the anchor and buoyed at the water's surface. The latch ring consist of a tail which attaches to the mooring line and a ring which slides downward along the crown line. The anchor post has an anchor collar coupled thereto which forms an annulus groove with the anchor post. The annulus grove latches the ring of the latch ring to the anchor post while the tail of the latch ring prevents the ring from detaching from the anchor post and riding backward up the anchor post once the latch ring is latched.
